Modern collaborative robots (cobots) are an important trend in industrial automation and smart manufacturing. Compared with traditional industrial robots, cobots focus on human-robot collaboration, safety, flexible automation, and adaptability. They are increasingly used in electronics assembly, medical equipment, AGV trolleys, logistics automation, and intelligent warehouse applications.
To meet these needs, collaborative robots require motors that are compact, high-torque, low-noise, and energy-efficient. These motors must support precise motion control, long service life, and stable performance under continuous operation. BG Motor, a professional DC motor and robotics motor manufacturer from China, provides brushless DC motors (BLDC motors), DC brushed motors, planetary geared motors, and robot drive motors widely used in industrial robots, servo motor replacement, and automation equipment.
A European robotics manufacturer planned to launch a new collaborative robotic arm for precision assembly and intelligent production lines. Their main challenges included:
High torque and small size motor to fit the compact joints of the robot arm.
Ultra-low noise and vibration to meet ISO 10218 safety standards for human-robot cooperation.
Long life and reliability for 24/7 industrial operation.
High-precision speed and position control for smooth motion like a servo motor.
Energy efficiency and compliance with CE, RoHS, and eco-friendly motor requirements.
BG Motor provided a customized brushless DC planetary geared motor solution:
Compact high-torque BLDC motor: 42mm diameter motor with an integrated planetary gearbox delivering high torque without increasing the size of the robot joint.
Low noise and low vibration: ≤40dB and ≤6.1 mm/s², perfectly meeting collaborative workspace standards and reducing human discomfort.
High-precision motion control: Encoder feedback supports closed-loop control, smooth start and stop, and accurate joint positioning.
Long life and reliability: Optimized bearing structure and insulation design up to IP65 ensure continuous-duty performance and minimal maintenance.
Integrated plug-and-play solution: Motor with gearbox, encoder, and optional driver simplifies system integration for robotics and industrial automation equipment.
After using BG Motor’s solution, the robotic arm achieved 30% smoother movement, 20% lower noise, and higher energy efficiency, meeting the flexible and green automation requirements of modern factories.
BG Motor provides complete service for robotics and industrial automation motors:
Motor performance test reports and torque-speed curves for every batch to ensure quality and performance verification.
Professional engineering support for installation, debugging, and integration into motion control systems or servo motor replacements.
Long-term warranty and spare parts supply, with fast response to technical issues to ensure stable operation for robot manufacturers.
With BG Motor’s high-performance DC motors and customized automation solutions, the collaborative robot project entered mass production successfully, helping the customer achieve intelligent, flexible, and safe automation for global markets.
